Kata,
Frankly, it depends on what you like. I've owned Fender, Hartke, Ampeg, Crate, Peavey ... etc., you name it. It all depends on what you're looking for and what you like. I'd recommend you focus less on brand and more on sound. If a decent Ampeg rig gives you the sound you want, then go with it. On the other hand, if an F1X, or and Ashdown, or Eden, or custom made setup, etc. gives you the sound you're looking for, go with that. Speaking only for myself, I'm always open to better rigs. Right now, I'm using Ampeg because it works for me. I used Hartke prior to that. Who knows? Maybe later I'll find something better.
My recommendation is you try out a lot of gear if you can. Then pick what's the best for you based on your needs and wants. Eventually, you'll settle on something you like.
If you have the wherewithal and you have friends who own different stuff, you might want to try your Alembics through their equipment. If not, go to as many music stores as you can who have gear you're interested in and try your instrument through them. You'll probably find something you like if you haven't already.
Speaking only for myself, I had my Ampegs before I got Alembics. I've been happy with them so far. To each his/her own I always say.
Best of luck,
Alan
